Transient growth and nonlinear breakdown of wavelet-based resolvent modes in turbulent channel flow

Eric Ballouz, Scott T. M. Dawson, H. Jane Bae

We study the effectiveness of the time-localised principal resolvent forcing mode at actuating the near wall cycle of turbulence. The mode is restricted to a wavelet pulse and comp…

Wavelet-based resolvent analysis of non-stationary flows

Eric Ballouz, Barbara Lopez-Doriga, Scott T. M. Dawson +1

This work introduces a formulation of resolvent analysis that uses wavelet transforms rather than Fourier transforms in time. Under this formulation, resolvent analysis may extend…

Sparse space-time resolvent analysis for statistically-stationary and time-varying flows

Barbara Lopez-Doriga, Eric Ballouz, H. Jane Bae +1

Resolvent analysis provides a framework to predict coherent spatio-temporal structures of largest linear energy amplification, through a singular value decomposition (SVD) of the r…

Transient growth of wavelet-based resolvent modes in the buffer layer of wall-bounded turbulence

Eric Ballouz, Scott T. M. Dawson, H. Jane Bae

In this work, we study the transient growth of the principal resolvent modes in the minimal flow unit using a reformulation of resolvent analysis in a time-localized wavelet basis.…

A sparsity-promoting resolvent analysis for the identification of spatiotemporally-localized amplification mechanisms

Barbara Lopez-Doriga, Eric Ballouz, H. Jane Bae +1

This work introduces a variant of resolvent analysis that identifies forcing and response modes that are sparse in both space and time. This is achieved through the use of a sparse…

Wavelet-based resolvent analysis for statistically-stationary and temporally-evolving flows

Eric Ballouz, Barbara Lopez-Doriga, Scott T. M. Dawson +1

This work introduces a formulation of resolvent analysis that uses wavelet transforms rather than Fourier transforms in time. This allows resolvent analysis to be extended to turbu…
